Intra-Golgi Transport: Roles for Vesicles, Tubules, and Cisternae

Figure 2

Cryosection of the Golgi complex of a rat exocrine pancreatic cell. Face view of a single cisterna (G) showing the huge complexity of the surrounding tubulovesicular elements (asterisk). Without a detailed immunocytochemical analysis of their composition and high-resolution structural study, it is not possible to discern whether these membranes represent the ERGIC, CGN, peri-Golgi vesicles, or tubules connecting the stacks laterally. N = nucleus. Bar = 200 nm.
